It can also be fitted to the WLA-11 weather louvre aluminium grille . The opposed blade damper is held in place by special pat- ented clips, designed both for fixing the damper to the grille and for fitting it on a mounting frame or a plenum PBA. The DGA dampers are made entirely of galvanized steel and have mechanism for opening and closing all the damper blades simultaneously (by using a screwdriver). DGA is provided with spring wire to prevent the blades from clattering. Maintenance Remove the grille to gain access to the opposed blade damper or duct.
